Description

Technical Field

[0001] The invention relates to the field of keyboard manufacturing technology, and in particular to a Z-shaped bending mechanism for lead wires of a membrane keyboard. Background Technology

[0002] Membrane keyboards are a type of keyboard that has become popular internationally in recent years, combining aesthetics and functionality. They are aesthetically pleasing, novel in appearance, small in size, lightweight, and highly sealed, offering advantages such as moisture resistance, dust resistance, oil resistance, acid and alkali resistance, shock resistance, and long service life. They consist of a panel, upper circuitry, isolation layer, lower circuitry, and lead wires. The lead wires of flexible membrane keyboards are integrated with the switch body itself. When connecting multiple switches, they are gathered at a specific point on the membrane and extended outwards according to the designed position and standard line spacing, serving as flexible, bendable, and sealed lead wires that connect to the rear circuitry of the entire device. To reduce the overall size of the membrane keyboard, the lead wires need to be zig-bent before connecting to the rear circuitry for subsequent keyboard assembly.

[0003] Existing methods for Z-shaped bending of membrane keyboard leads mostly involve manual bending, and there is a lack of devices specifically designed for Z-shaped bending of keyboard leads on the market. Manual bending results in long assembly time, low work efficiency, and poor consistency of leads after manual bending. Therefore, we have invented a Z-shaped bending mechanism for membrane keyboard leads. Summary of the Invention

[0062] Please refer to the above structure and process. Figure 1-2 .

[0063] The first linear slide 301 is activated, causing the mounting bracket 302 to move closer to the placement plate 2. The mounting bracket 302 then moves the flip plate 309 to the placement plate 2, at which point the keyboard lead wire is positioned on the upper surface of the flip plate 309. The first cylinder 403 is activated, causing the limiting mechanism 6 to move downwards via the mounting plate 5. The limiting strip 608 on the limiting mechanism 6 moves above the keyboard lead wire. The second linear slide 606 is activated, causing the limiting strip 608 to move downwards via the lower mounting base 607. 08 moves downwards, and the limiting strip 608 contacts the bottom of the keyboard lead wire, limiting the bottom of the keyboard lead wire. The first motor 303 is started, and the first motor 303 drives the output shaft to rotate. The output shaft drives the transmission shaft 304 to rotate through the synchronous belt. The transmission shaft 304 drives the rotating shaft 308 to rotate through the first connector 305, the connecting rod 306, and the second connector 307. The rotating shaft 308 drives the flip plate 309 to flip to one side of the placement plate 2. The flip plate 309 drives the keyboard lead wire to flip and rotate. At this time, the end of the keyboard lead wire is raised upwards.

The pressure roller 704 performs the first rolling pressure on the back of the keyboard lead wire. After the first rolling pressure is completed, the pressure roller 704 and the flip plate 309 are reset.

The limit bar 608 contacts the middle of the keyboard lead wire and limits the middle of the keyboard lead wire.

[0066] The second cylinder 705 is activated and retracts. Under the action of the torque spring, the deflection plate 703 drives the pressure roller 704 to move downward. Then, the slide cylinder 701 is activated. The slide cylinder 701 drives the pressure roller 704 to move towards the end of the keyboard lead wire through the connecting plate 702 and the deflection plate 703. At this time, the pressure roller 704 contacts the end of the keyboard lead wire. Then, the slide cylinder 701 drives the pressure roller 704 to move back and forth. The pressure roller 704 performs a second rolling press on the front side of the keyboard lead wire. After the second rolling press is completed, the pressure roller 704 and the limit bar 608 are reset.

[0067] The third cylinder 802 is activated, which drives the pressing plate 803 to move downward. The end of the pressing plate 803 presses the keyboard lead wire after the second bend, thereby completing the Z-shaped bend of the keyboard lead wire.
